Agreed, great thread! I've read most of it but lost track of what was posted on which page. Can someone (Eddie maybe?) summerize what needs to be done and/or checked on a 525 broken down by hours or seasonally? Or point me in the right direction if its already posted somewhere.

I have an eliminator Daytona. 401 hours with nothing but impeller, oil, fuel/water filters, drive oil changes. 90 mph boat any day of the week. Motor and boat model year 2005. Two c1f1 shoot out trophies, the 525 eliminator that ran in my class went 11 mph slower I think.
My fathers boat with merc 700's and 190 hours (42 lightning). Two computers from burned out iac circuits, 3 iac motors, one nxt tranny, one #6, and it always sticks in gear (reverse).
We both do our own service and his has special motor oil and expensive drive oil.
So I say ilmor all the way.

We have found that Amsoil seems to work the best of the oils we have used. We have even seen a few HP increase while dyno testing. The Amsoil gear lube is also awesome, ran it all last yr and every time we sent the drive out for inspection Craig said it was excellent very clean and even wear.

Eddie I'm not sure the yr that Crane was having issue either, from what I have heard the steel they are using is the issue. I have heard and seen the rockers from many different builders and the story is the same. This isnt really a big deal there are plenty of other rockers out there that will do a great job.

425 hrs with zero issues. Planning to do springs and seals this fall. Never header issues that many have experienced I had researched and came to the conclusion of 300 for HP500s and 500 for 525s assuming no header issues
